Cypress Semiconductor integrates Ramtron F-RAM nonvolatile memory Cypress Semiconductor (CY) has integrated Ramtron (RMTR)’s ferroelectric random access memory products into its portfolio. F-RAM is the industry’s lowest-power nonvolatile memory. This new combination serves a broad range of applications that require data to be retained when power is lost. The merger between Cypress and Ramtron was officially completed on November 20. Cypress is maintaining Ramtron part numbers. There will be no supply disruption for more than 95% of production parts.
